Environment

VMware Cloud Foundation 9.0

Cause

VCF Operations fleet manager cannot reach the DNS server.

Resolution

Ensure the Fleet Manager appliance has a clear network path to the DNS servers:

1. Verify Network Connectivity: Log in to the Fleet Manager appliance via SSH and attempt to ping the DNS server.
2. Check Firewall Ports: Ensure UDP Port 53 is open between the VCF Operations management network and the DNS server.

    

3. Check if the DNS Ports are open.
   The Connection will fail/refuse while trying to access the DNS server via port 53 if the ports are closed.

   root@vcf [ /var/log/vmware/vcf/domainmanager ]# curl -v telnet://<DNS-IP>:53
*   Trying <DNS-IP>:53...
* connect to <DNS-IP> port 53 from <DNS-IP> port 59678 failed: Connection refused
* Failed to connect to ###.###.###.### port 53 after 0 ms: Could not connect to server
* closing connection #0
curl: (7) Failed to connect to <DNS-IP> port 53 after 0 ms: Could not connect to server

   OR 

   root@vcf [ /var/log/vmware/vcf/domainmanager ]# nc -zv <DNS-IP> 53
fqdn.com [DNS-IP] 53 (dns): Connection refused

4. Check the DNS records updated in the SDDC manager, Remove the DNS record if the added DNS IP is are not reachable. 
5. Once connectivity is ensured, re-try the deployment task from the installer.
